The LG LJ5500 is an entry-level 1080p smart TV which features LG's WebOS platform. It has a relatively wide viewing angle, making it better than average for use in a wider living room. Unfortunately, its picture quality leaves a lot to be desired, and its 1080p resolution is a bit antiquated. It is the same TV as the LJ550M found at BestBuy and the LJ5000 and LG500M are variants without smart features.

Our Verdict

6.0 Mixed Usage

Poor TV for a mixed usage. The LG LJ5500's shortcomings stack up well above its positives, and its below average picture quality greatly reduces its capabilities with every usage.

See our Mixed Usage recommendations
5.1 Movies

Not a good TV for watching movies in dark room. The LJ5500's blacks are shallow and very cloudy making them quite distracting, and its 1080p resolution means it cannot fully take advantage of modern content.

See our Movies recommendations
6.7 TV Shows

Average TV for watching cable or broadcast television. The LJ5500 gets bright enough for most rooms, and it handles reflections decently. Its WebOS smart features also make it easy to access content. Unfortunately, static content such as network logos are retained for a few minutes, and the overall picture quality is subpar.

See our TV Shows recommendations
6.9 Sports

The LJ5500 does a decent job with sports broadcasts. Its wide viewing angle means watching it from the sides won't affect the picture quality too much, and it handles fast motion quite well. Unfortunately, its uniformity could be better, and static on-screen content can sometimes be retained for a few minutes.

See our Sports recommendations
6.9 Video Games

Passable TV for gaming. The LJ5500 has low motion blur, so fast motion doesn't have any distracting trails. Its input lag is also fairly low, which keeps games responsive and immersive. Unfortunately, the TV's poor overall picture quality reduces the quality of the experience.

6.7 PC Monitor

Mediocre TV to use as a PC monitor. While it is capable of 4:4:4 chroma and has no major issues with viewing angles, its 1080p resolution is less than ideal for productivity and its input lag could be better. It also lacks niche features like a 120hz input.

Curved No

The design of the LJ5500 is basic and similar to most other LG TVs is the 6 series such as the UJ6300. It won't stand out in a room but is functional with quite easy to access inputs and has a wide stand that supports the TV well.

Design
Stand

Similar to most other LG TVs, the LJ5500 has a stand almost as wide as the TV. It is made of plastic but does support the TV well.

Footprint of the 43" TV stand: 7.3" x 33.4"

Design
Back
Wall Mount VESA 200x200

The LJ5500 has a simple plastic back. It does look a bit better than most low-mid range TVs due to the molded plastic. Most of the inputs are out the side of the TV and so easy to access if placed close to a wall, but legacy inputs may be difficult to connect when wall mounted.

Design
Borders
Borders 0.71" (1.8 cm)

The borders of the TV have an average thickness, but look quite good due to the smooth plastic.

Design
Thickness
Max Thickness 3.27" (8.3 cm)

The TV appears quite thick when viewed from an angle but this isn't too much of an issue. It will stick out slightly if wall mounted.

Temperature

The front of the TV stays fairly cool, and the back only gets warm to the touch in a few spots, the warmest being near where the power cord plugs into the TV.

The build quality is decent. Everything is made of plastic but fits together quite well without too much play. It is not likely to be an issue with normal use.

Contrast

Contrast with local dimming
N/A

The LJ5500 has a sub-par native contrast ratio for an LED TV. When compared to other IPS TVs though, with a contrast ratio of 1140, it is in the middle of the pack for this type of panel.

This low contrast ratio means that when set in a dark room, the blacks won't be very black, but will look more like gray than really black. Fortunately, this is less noticeable when the TV is set in a room with a good lighting since the room ambiant light will render less noticeable this low contrast ratio.

The LJ5500 overall gray uniformity is average. Looking at our 50% gray uniformity picture, the main thing that catches the eyes is the 2 brighter spots in the top left part of the screen. The corners and sides are also a bit darker than the rest of the screen and the bottom part is a bit warmer than the top. Dirty screen effect is visible, unfortunately, especially while watching sports like hockey of soccer.

The uniformity in the darker shade of gray is much better than the 5 percent though, and not much can be noticed at all on that aspect.

The LJ5500's black uniformity is bad. Some flashlighting is visible near both top corners. Some clouding was also visible here and there with some darker patches near the lower corners. Overall, the screen is not very uniform and this will be particularly visible in dark scenes in movies or TV shows.

The reflection handling of the LJ5500 is quite good. It has a semi-gloss finish which diffuses direct reflections across the screen, reducing their intensity. It is fine for an average room, but in a bright room, reflections may be an issue.

Out of the box, when the LG LJ5500 is set to the 'Expert (Dark room)' picture setting, and with the 'Warm2' color temperature, the overall accuracy is below average. If the TV is set to another picture mode or one of the other color temperature, then the accuracy is even more disappointing.

The white balance is a bit on the warmer side, but just slightly, and the dE is higher than what we would like (4.16), as an avid enthusiast could notice there is something a bit off here. The gamma is not too bad though since even if the curve is not flat, we still end up with 2.22, which is not too far from our target. The only small issue with the gamma is in the lower stimulus level, where the TV might loose some contrast in the very dark region, but besides that, it looks good.

The color accuracy is also a bit high with a dE of 3.91. Most of the issues here derive from the fact that the white point is a bit off and thus, all the other colors follow. Only the yellow and blue are a bit more off target than the rest.

After calibration, the LJ5500 shows excellent accuracy. Both the white balance dE and color dE are much more precise and accurate. There is only a small imperfection in the lower stimulus, but this did cause a problem and we could not fix it without causing more trouble.

The only downside here is that the whole process was pretty inconsistent, as the 2 point, 20 points white balance and color space management were not very accurate and responsive. In the 20 points white balance control, each point was affecting up to 2 or 3 points higher, make the whole process a bit longer. This was a bit of a surprise, as much of the 2017 LG line up that we did calibrate had very responsive and precise control over the white balance.

In the end, the calibration was still a plus and the result was good, but it only took a bit more time to do than usual.

Upscaling of low-quality content such as DVDs is quite good. The image is a bit softer than usual, but edges remain defined.

The LG LJ5500 performs excellent on our gradient test. Almost no banding at all can be seen on our test picture, besides some little irregularities in the dark green. No 8-bit banding can be seen at all. This is one of the best gradients with have tested yet in 2017.

The LG LJ5500 IPS TV does present some image retention. After the 10 minutes burn-in scene, as we can see on our test picture, the image retention is easily noticeable, but after 2 minutes of recovery, the retention is already very faint and almost non-noticeable.

Even if this result is disappointing, overall, when you compare to other TV, VA panel TVs especially, the fact that the retention clears up pretty fast is good news and when compared to other IPS TVs tested before, the LJ5500 would be in the middle of the group performance wise.

PWM Dimming Frequency
120 Hz

The LG LJ5500 uses PWM at 120Hz to dim the backlight, starting at 100/100 backlight setting. Lowering the setting shortens the duty cycle, while amplitude remains constant. Backlight PWM helps clear up motion slightly, but results in duplicate images following fast-moving objects, visible in the motion blur picture.

Great low input lag, which should please all but the most competitive gamers. The 'Game' picture mode has the lowest input lag, even in PC mode. PC mode on most other LG TVs has low input lag for all picture modes, but this is not the case with this TV, as only the Game picture mode has low input lag.
